HAND-muss For. SHAETING.

To all whom it may concern .1 7

Be 1t known that I, HENRY O. URBANER, a cltlzen ofthe United States, residing at Naperville, in the countyof Dupage, Stateof, Illinois,"hav einvented ;a new and useful Hand-Press, for Shafting; and I do hereby fdeclare the following-to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to hand presses and 'hasfor its object toprovide a hand press particularly adapted for use lllfilltOHlObllB repair shops, blacksmith shops and the like sothat a piece of shafting may be straight ened easily and quickly by applying pressure to the particular bend at aproper radial direction to the centerofthe shafting'.

Also to provide means for supporting the shaftingso that the same maybe easily rotated and the bend ascertained-and marked. A further object is to provide a hand press for shafting wherein the frame isbuilt up and formed from. asingle piece of channel lIOIl bent upon itself so asto form a substantially U-shaped frame,,,the flanges of the tering elongated Qslots. through the] ends.

thereof adapted to acooperate. with the notches in the outwardly extending flanges r of the vertical portions of the frame, said elongated slots and bolts being sopositioned' that the bars maybe forced cupwardly at one end so as to clearthe bolt "atthat-end from the notches and then lowered so that the cleared bolt will'enter the notches below and adjacent the notches that-the bolt has cleared. The elongated slots allow the bars,

, whenoneend thereof hasbeen lowered, to be forced into the opposite direction so-that the bolt in'the notches of the other vertical portion of the frame, may becleared from its notches and lowered to theadjacent notches so thatthe bars maybe supported Specification of Lette rs Patent.

in-. horizontal position or if so desired E151- fworked farther down. Also to provide bolt and notch supporting means for the .bars, said notches being so constructed thatthey will force the bolts outwardly in elongated I sgre' l ear eegggpvvslots in the bars so that the bars may be worked upwardly as desired.

I With the above and other objects inview the invention resides in the combination and arrangement of parts; as. hereinafter setforth, shown in the drawings, described and claimed, it be ngunderstoodthat changes 1n the precise embodiment of the inventionmay be made within the scope of. what is claimed without departing from the spirit of 'theinven'tion.

a horizontal position.

Referring to, the drawings, thenulneral 1 designates 'a .U-shaped frame a'ndf2;the upright portions thereof, wlnchportmns"are in parallel relation to each otherLjTh'eU- shaped frame'ris formed from' channelii-ron' and so. formed that its flanges will bei o'ut- 11 0 wardly vdisposed. The upper end of the v w U-shapedjframe 1 is bentatB a-ndai-so as I an integral brace.

to form the arching portion 5, however, it has been found that by bending the channel iron as at 5, the material is stretched and is partially fractured, therefore to overcome this difliculty a transversely disposed bar 6 is provided. The ends of the bar 6- are welded to the frame at the bending points 3, thereby building up these points whichhave become weakened, bracing the frame transversely and at the same time forming Secured to the lower ends of the vertical members 2 are angle irons 7 which form a base for the machine as a whole, said angle 110118 having their ends secured together by brace rods 8 so as to form a firm base for 'the'machineas a whole.

' The flanges 9 of the vertically disposed portions 2, of the frame are provided with .registering inclined notches 10, said notches 'and'the flanges of each portion 2 being at the same height from the base and forming -'1neans for supporting bars 11 and 12 in a horizontal plane. The horizontal bar 11 is supported in notches 10 by means of bolts v 18, said bolts being disposed in'elongated slots 13, so that by manipulatingthe bar 11 said bar may be worked upwardly or downwardly to notches at various heights from the ground. The horizontalbar ll'has slidabl-y mounted thereon brackets provided with center points 14 for supporting a shaft during a truing operation, when said shaft is. provided-with center depressions in its ends, therebysupporting the shaft so that it may berotated and theparticular point of bend ascertained and marked. However, where the shaft is not provided'with centers at its ends so' that it can'be supported by the centering points 1%, the shaft is placed upon the rotatable wheels 17 as indicated at 18 in Figs. 5 and Gandrotated thereon so that i the :point of bend may be ascertained and marked. Bars 12 are supported in a horizontal position by means of bolts 19 which pass through elongated apertures 19 in the ends of said bars, and through the registering notches 10, which extend downwardly and inwardly from the outer edges of the flanges 9. hen it is desired to lower the bars 12 which bars are of considerable weight, it will be seenby referring to Figs. 7, 8 and 9,

that as the ends a of the bars are forced upwardly that the bolt 19 at saidendwill be forced into the outer end of the elongated apertures 19 and the bars 12 also moved laterally. The end a havingbeen raised,

said end is lowered to the position shown in Fig.8 and the bolt 19 disposed in the in clined notches 1O adj acentthe notches 1O from which it has 311st been removed. The bars 12 after having been placed in the positions shownin Fig. 8 are then forced'to one side in the direction of the arrow 0 so that the bolt'l9 at said other side may be moved out of engagement with the notches 10, and that end of the bars lowered as shown in Figs. 9.

It may be seen by referring to Fig. 9 that the end 0 of the bars may be lowered so that said bars will be in a horizontal plane, or if so desired may be further lowered, so that the bars may be worked to a horizontal theshaft 18 is disposed W1tl1' its particular; 7

point of bend centrally disposed'be'tween the blbcks 21, in whichposition it will beengaged by the straightening element '22 carried by a vertically dispose'd'threa-ded'shaft 23, said shaft 23 being slid'ablyf mounted in a bearing 24Lof-the bracket 25 and in a-bearing 26 of the bar 6. Threaded on theshaft 23 and disposed'between the'bracket'25 and f the bar 6 is a gear 27, which gear is a beveled one, and when rotated will threadup- 'wardly and downwardly on the threaded shaft 23 so as to *move'engaging element/22 into engagement with the shaft carried by the blocks 20,-sothat said shaftmay'bebent in such a manner as'to remove bends-therefrom; Meshing withth'e gear 27 is a beveled 1 gear 28, whichbeveled gear is secured on a shaft 29, said shaft being rotatably mounted in a bearing of thebracket 25 and inabearing of the frame -1. The other end of the shaft 29 has secured thereto a wheel 30 which is adapte'd'tobe graspedbythe'hand of the operator for rotating the beveled gear 27, so that the bending'element22 will be moved downwardly or upwardly as desired.

The upper endof'the threaded shaft 23 is provided with a "transversely disposed pin 31. mounted in vertically disposed slots 31 so as to insure the vertical movement of the V shaft 23 and also to limit the downward movement of said shaft. However, ithas been found in *machines of this type where "a collar or pin is used for limiting the The ends of said pin being slidably downward movement ofthethreaded-shaft, V

7 that said pin or collarwill be sheared off unless the operator is extremely careful. To overcome this difiiculty a spring-supported pivoted lever 32 is'provided, which'lever has one of its armsextending-inwardly so as-to be disposed in one of slots 81*, so thatthe end of the pin 31 on its downward movement will cause the-other end of-the lever which is disposed within a bell tobe moved against the action of the spring 34 and can pass the engaged end 0f the-lever32, sothat an alarm will be soundedwarning the operator that the machine has reached thefend of its stroke.
